Hi Steven, here are excerpts from the article you sent:

Despite the fact that several studies have been conducted, with regards to ability of creative imagination in animals, nothing substantial has been proven till date.

Studies indicate that animals can imagine to a certain extent, assume the existence of non-existent things, or pretend that one object is another, and act accordingly. However, it is ambiguous as to whether these things reflect the imaginative powers of animals or their basic instincts, such as distracting a rival’s attention. In the absence of solid evidence, it is very difficult to say whether animals have imagination or not.

I don’t think that is evidence that I am wrong. Though I would not be surprised if we discover evidence in the future.
